I got BT4 running on 4g usb pendrive OK just short of space.
Got 8gb sdhc card and formated all OK on eeepc using BT4.
Problem is when I boot live cd or 4g usb drive the sdhc card does not show in fdisk -l or dmesg. The sd card is partitioned and formated OK.
tried echo 8 > /sys/module/sci_mod/parameter/max_luns still does not show.
Also now got it working on 8gig usb pendrive ok. Any ideas as sd card easier to use in eeepc.
